At this point, the lossless compression
algorithm is applied to compress the image.
 Recommendation G.711.0, Lossless compression
of G.711 pulse code modulation, ITU-T, 2009.
It provides a lot of functionalities such as a unique codec for lossy and lossless compression
, resolution and quality scalability, partial/full encryption, 2D region of interest coding, rate control, and rate-distortion optimization .
We regard the lossless compression
system as a chaotic cryptosystem.
- Display Stream Compression (DSC 1.2) for interoperable, visually lossless compression
over display links;
Compression algorithm mainly has two kinds: one kind is reversible, that is, from compressed data can be fully recovering the original data, without any information loss, called lossless compression
; Another type of compression is irreversible, that is and from compressed data can't fully recover the original data, information has a certain loss, called the lossy compression.
Audio Codec Market by Component (Hardware and Software), Channel Type (Mono-Codec, Stereo Codec, and Multi-channel Codec), Compression Type (Non-Compression, Lossless Compression
, and Lossy Compression), Application, & Geography - Global Forecast to 2022
This brings improvements to the existing 2:1 compression and adds two new forms of lossless compression
- 4:1 and 8:1.
In lossless compression
, the file, if uncompressed, should contain all the original data.
For users who need all spatial and spectral pixel content retained, lossless compression
to 50 per cent of original file size is possible.
PSNR is used as a general metric to measure the quality of restoration of lossy or lossless compression
Text compression is a field of data compression, which uses the lossless compression
technique to convert an input file to another form of data file.
